All three designs have something going for them, but all three also have significant shortcomings that could fuck them over>SIG
Two charging handles for no reason, the rear handle means you can't do much fancy cheek riser shit with the stock.
Also, ammo pressure necessitates a fucking steel at the base of the cartridge.
Most likely to be adopted, and most likely to get a civilian version.>GD
Neat design, neat chode suppressor, heavy as fuck for no reason. Half-assed LMG concept, literally just a lengthened barrel>textron
Best ammo design, worst firing mechanism, ejects out the bottom front for no fucking reason using a bizzare linkage system.
They really ought to be going for a bullet shape with a high BC, needle dick bullets do alot of tumbling in the body and preserve energy better than a fat potato bullet.
